Salt System newbie

BTDG:

Relax: there are situations where higher CYA levels are called for. aylad runs her pool high because there's SO much loss due to sun and biologics she needs more stabilization. So she compensates by running a higher residual FC level.

But SWGs need higher CYA levels and lower FC levels. I'm not sure of all the chemistry, but years of watching the SWG people has me convinced.

The key is being able to turn down your SWG on-time. The higher CYA level should let you do that by greater protection of chlorine from breakdown by sunlight. It's not the higher CYA itself that slows down the rate of pH rise -- it's the turning down of the SWG on-time (i.e. the % on-time) -- the higher CYA is just one way to be able to do that.

Yes Chem Geek I agree, you are absolutely correct. I was instructed by the installer to simply run the SWCG for 12 hours a day and forget about it. This took me out at the knees. How does not buying Chlorine tablets save you money if you are spending more than the price of chlorine on your electric bills every month, or if you're pouring gallons of acid into your pool every week? So learning from knowledgeable people is worth its weight in gold.

CarlD, I do realize that different locations, different pool types, and different situations will all affect pool chemistry. My pool is 20 miles east of Phoenix and I am sure that I have my own unique situation to learn and understand. I am relaxed, I am listening, and I am learning, I am still on start-up, I am still a salt system newbie, and don't forget, I am still a BTDG too. LOL. Thanks for your help. We're cool.
